Revert "No hardcoded path for $ENV{GENOME_TEST_URL}"

This reverts commit 9888693365584cac823ecf3239b01210d8d7d731.
Set NO_LSF so test's workflows run inline.
use /tmp instead of GENOME_TEST_TEMP

Logic in Genome::Disk::Alllocation::_get_mount_path_from_full_path fails
if the test's volume's mount_path is a subdirectory of another volume.
Add new releases for bowtie and tophat.
make test more resilient

- No longer diff the PNG files since they can differ for irrelevant
  reasons.
- Improve the diff of the config file to remove a dependency on file
  paths.

alter tests to diff less aggressively

There were several tests that broke when we changes the GENOME_TEST_TEMP
directory path. A few were fixed already but these are a few more. In
most cases this was improved by filtering out certain lines from output,
e.g. paths and timestamps.
Reapply "No hardcoded path for $ENV{GENOME_TEST_URL}"
use compare for files, instead of compare_text
add Genome::Utility::Test
remove "broken" tests

compare returns 0 when there are no diffs so this was testing that the
files were different; not the same.
fix diff test

I didn't notice that the test earlier was text and not files.
add basic docs
unset NO_LSF for this test
Added the option to create a stacked bargraph in additon to dodge barplot
